| Zizindikiro Zowopsa | Xi - Zosangalatsa |
| Zizindikiro Zowopsa | R20/21/22 - Zowopsa pokoka mpweya, kukhudzana ndi khungu komanso kumeza. R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. |
| Kufotokozera Zachitetezo | S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S36 - Valani zovala zoyenera zodzitetezera. |
| Zowopsa | Zokwiyitsa |
Mawu Oyamba
Ndi organic pawiri ndi formula C7H3BrClF3. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha pawiri:
Chilengedwe:
-Maonekedwe: madzi opanda mtundu
- Malo osungunuka: -14°C
-Powira: 162°C
-Kuchulukana: 1.81g/cm³
-Kusungunuka: Kusungunuka mu zosungunulira organic monga ether ndi dichloromethane, sungunuka pang'ono m'madzi
Gwiritsani ntchito:
- imagwiritsidwa ntchito kwambiri ngati gawo lapakati pakupanga organic, makamaka m'minda yamankhwala ndi mankhwala ophera tizilombo.
-Zitha kugwiritsidwanso ntchito ngati zovuta mu asymmetric synthesis, catalysts ndi makhiristo amadzimadzi.
Njira Yokonzekera:
Zopangidwa ndi zotsatirazi:
1. Choyamba, 2-chlorotrifluorotoluene (C7H4ClF3) imakhudzidwa ndi sodium nitrite-N-acetamide complex kupeza 2-nitrotrifluorotoluene (C7H3NO2F3).
2. 2-Nitrotrifluorotoluene imakhudzidwa ndi hydrogen bromide, ndiyeno gulu la nitro logwira ntchito limasinthidwa ndi gulu la bromine logwira ntchito pogwiritsa ntchito m'malo mwake kuti apeze gulu la nitro.
Zambiri Zachitetezo:
- ayenera kukhala organic pawiri, amene ali ena sensitization ndi kawopsedwe. Chonde tcherani khutu ku ntchito yolondola ndi kusunga.
- Kugwiritsa ntchito ayenera kuvala zodzitetezera magolovesi, magalasi ndi zotetezera kupewa kukhudzana ndi khungu ndi kupuma mpweya.
- Pewani kukhudzana ndi ma okosijeni amphamvu, ma asidi amphamvu, ma alkali amphamvu ndi magwero amoto kuti mupewe zoopsa.
-Gwirani ntchito pamalo abwino mpweya wabwino, kutali ndi moto ndi kutentha.
-Mukakhudza kapena kumeza, pitani kuchipatala msanga.
